Offside pass

An offside pass (also known as a "two-line" pass) occurs when a member of the attacking team passes the puck from behind his own defending blue line to a teammate across the center red line. If the puck precedes the player across the red line, the pass is legal. Also, an attacking player may pass the puck over the center red line and the attacking blue line to a teammate if the puck precedes that teammate across the blue line. The face-off after an offside pass takes place at the spot where the pass originated.
